Just finished pulling the flywheel from my JLO L300, and thought I'd write about the "experience" in hopes of encouraging others with a stubborn flywheel. I read the horror stories on this site before attempting "the pull". So, I borrowed a three point puller that boltes up to the three bolt holes that hold the rope winding collar. After trying unsuccessfully to pull "dry", I turned the engine on its side so that the crank shaft was perpendicular. Then I sprayed Liquid Wrench into the recess where the 27 mm nut sits that holds the flywheel on (you can see part of the key down in there after you unscrew the nut and remove the lock washer). I really filled that recess and was prepared to wait a day (or two) and then return to try to pull again. Much to my surprise, the level of the Liquid Wrench started to drop as I was sitting there. So, I filled that recess up again. It drained again so I filled it again. This all took about 5 minutes. So, I uprighted the engine, attached the puller, and started rapping on the end of my box wrench with sharp blows (just held the flywheel by hand to resist the instantaneous torque from the blows). Much to my surprise, the flywheel started moving towards the end of the shaft after only about a minute of rapping.
The moral of the story is: don't give up, use plenty of Liquid Wrench, and use sharp impacts (like recommended in another thread somewhere on this site). And, if you're so inclined, say a prayer that the Good Lord will help you like He did for me. Hope this helps someone out there!!
